I might be interested, I have not touched osrs since GIM release, had a group with 2 friends back then but they both stopped fairly fast. Also have a 2k total main I used to play before GIM release.
Never did any bossing, also dont remember a whole lot, would have to get back into it and remember lots of the stuff I used to know, but generally I'd like to give GIM another chance with maybe a bit more dedicated people than my RL friends.
